The Meaning of "Fundamental" in Music
In music, the term "fundamental" refers to the lowest pitch or frequency of a note that is perceived as the lowest partial present. It is the musical pitch that serves as the foundation or basis for a particular sound or chord. The fundamental frequency is the lowest frequency of a periodic waveform, and it is considered one of the harmonics in a harmonic series, which is a set of frequencies that are positive integer multiples of a common fundamental frequency.
The fundamental frequency can be created by the vibration over the full length of a string or air column, or it can be a higher harmonic chosen by the player. It is also the root of a chord and the generator of a series of harmonics. In terms of a superposition of sinusoids, the fundamental frequency is the lowest frequency sinusoidal in the sum of harmonically related frequencies or the frequency of the difference between adjacent harmonics.
In summary, the fundamental in music refers to the lowest pitch or frequency of a note that serves as the foundation or basis for a sound or chord.
1. A base pitch from which a series of harmonics is produced. 2. The base pitch upon which a chord is built.
